There appears to be no one definition of a trash ship*, so my definition is a ‘ship that you know is objectively bad, either because the characters bring out the worst in each other or because one of the characters is literally a cannibal serial killer (or somesuch). Cherik (Charles Xavier/Erik Lensherr)? Trash ship.Starbuck/Apollo? Trash Battlestar. Hannigram (Hannibal Lecter/Will Graham)? Trash spiral-galaxy.
